quantax.utils.Sqz_factor

quantax.utils.Sqz_factor(*q: float) → Callable

Spin structure factor \(\left< \frac{1}{2 \sqrt{N}} S^z_r S^z_0 e^{-iqr} \right>\)

Parameters:

q – Momentum of structure factor

Returns:

A function f that gives the structure factor of spin configuration s by calling f(s)
